1 '0 all whom it may concern:

Be it known that I, GUSTAF LEANDER HAL- VARDSON, a subject of theKing ofSweden, residing at Roslagsgatan 59, in the city of Stockholm, Sweden,have invented Means for Driving (Ringing) of Church-Bells and the Like,of which the following is a specification.

Means for mechanical ringing of church bells and the like with the aidof electric current are already known. But the arrangements of this kindhitherto used or proposed are encumbered with serious disadvantagesbeing bulky, heavy, expensive, little economic and liable to fail or getout of order, thus needing frequent repairs or changes of parts. By myinvention all these disadvantages are removed. I have attained thisresult by driving the bell by means of an electric motor, thebrush-rocker of which partakes in the movement of the rotor withinsuitable limits and by using a resistance which by means of acentrifugal regulator or the like is automatically in creased anddecreased so as to correspond with the actual want of current. A movablemagnetically actuated stopper is used for locking the brush-rocker inthe starting position when the current ceases.

In the accompanying drawings, Figure 1 is a schematic side view of thebell rung by an electric motor. Fig. 2 is a schematic view of the motoron a larger scale. Fig. 3 shows the automatic resistance on a largerscale. Figs. 4:, 5, 6 are diagrams of motor and resistance, the formerbeing series wound in Fig. 4, shunt wound in Fig. 5 and compound woundin Fig. 6.

concentrically with the pivots 2 of the bell 7c is fastened agrooved-wheel 3 or the like, to which power is transmitted from anelectric motor m by means of a chain-wheel 1 and a flexible member 1,consisting partly of a chain, partly of wire rope. At the point farthestfrom the motor the rope may be fastened to the grooved-wheel 3 so as toabsolutely prevent sliding. An extra gearing 9 may be used as shown inFig. 1 if there is not space enough for a wheel 3 of large diameter. InFig. 2 I have shown a motor with four poles. This number of poles issuitable, but other numbers may be used.

The brush-rocker 6 with brush holders 7 and brushes 8 is free to partakein the rotation of the commutator 9 and rotor 10,but for only about 1/4.turn. Its movement in both directions is stopped by a fixed stopper 12,which projects in the path of two lugs 13, 14 on the brush-rocker.

A pivoted stopper 15 (hook or the like) is actuated by a spring 17 or bygravity or both so as to catch the brush-rocker 6 and retain it in thestarting position (shown in Fig. 2), when the current is shut oil, ahook 16 on the brush-rocker being used for engaging the stopper 15 inthe form shown. when the current is let on, the stopper 15 isautomatically attracted by one of the magnets 11 so as to release thebrush-rocker.

Referring to Fig. 2 when closing the circuit (by means of the switch 67,Figs. 4, 5, 6,) the rotor 10 will first rotate some turnscounter-clockwise and thus cause the bell to make a short movement inone direction. The increasing resistance of the bell will soon force therotor to stop and to rotate clockwise. As the brush-rocker 6 thenautomatically shifts its position about 90 from the position shown onthe drawing (so as to bringing 14 to rest upon the underside of stopper12), the motor will be able to cause the bell to make a larger movementto the other side and after again having been stopped and returned astill larger movement to the first side and so on until the bell hasreached its ordinary amplitude of swinging.

If the motor is correctly proportioned with relation to the weight ofthe bell or wound with sufficient inner resistance and no great changesof pressure in the circuit are occurring, the device now described isall that is necessary for driving the bell. WVhen the ringing shallcease, the switch 67 must be actuated again so as to shut 011' the'current. The hook 15 thus released from the magnet will catch the hookl6 and lock the brush rocker in the osition shown in Fig. 2.

I will now dcscri e the automatic resistance 1' shown separately in Fig.3, the use of which, though not always necessary, will involve greatadvantages. Fastened to the rotating shaft 5 of the motor or adapted tobe driven by it is a tubular shaft 51 or the like in which is guided asliding piece 52 having lugs 58 projecting through longitudinal'slotsand pivotally connected to arms 54, ending with weights 55, which byforked links 56 are pivotally connected to the shaft 51. A spring 57passed into the tubular shaft tends to force the piece 52 outward so asto keep the weights 55 pressed toward the outside of shaft 51. The innersupport 58 for the spring may be fastened at different points along aslot 59 so as to adjust the tension of the spring. By means of a link 60the piece 52 is connected to an arm 62 pivoted at 61 the free end ofwhich slides along a series of contact pieces 63, connected to a seriesof resistances 64.

In the drawing I have shown a series of twenty-five contact pieces and aseries of 12 resistances, thelatter being connected to the firstthirteen contact pieces as shown while the twelve last contact piecesare connected to the twelve first contact pieces and thus to e theresistances but in reverse order so that the fourteenth piece connectswith the twelfth, the fifteenth with the eleventh, the sixteenth withthe tenth and so on. The thirteenth contact piece is connected to thebinding screw 66. The other binding screw connects with the contact arm62 which is insulated from link 60. The parts 62, 63, 64k, 65, 66 areinsulated from the frame of the apparatus. By means of the bindingscrews 65, 66 the apparatus is inserted in the cir cuit.

WVhen the motor stands still and the sliding piece 52 thus is in itsoutmost aosition, the arm 62 is in contact with the rst contact piece(the outmost to the right) and the current has to pass through the wholeresistance series so that only a weak current passes through the motor.The latter thus will run with low speed and the weights 55 will swingout but a short distance from the shaft 51 so as to move the arm 62 tothe next contact piece. A part of the resistance being thereby excludedthe current increases and the motor gets a greater speed so that theweights are removed farther from the shaft 51 and the arm 62 is pulledfarther to the left and the resistance is thus again decreased and thespeed of the motor increased. In this way the current increasessuccessively to its normal strength. The arm 62 is then in contact withthe intermediate (thirteenth) contact piece and the whole resistance isexcluded. If on account of accidentally increased tension the currentexceeds the normal strength and the motor thus runs still faster so thatthe arm 62 reaches the fourteenth or a following contact piece,resistance is again out in automatically so that the current isdecreased until the motor runs again with normal speed.
